BACKGROUND

Cabinets are typically constructed at a location remote from the site where they are installed. Such cabinets are usually attached to a vertical wall by conventional fasteners such as, for example, French cleats, screws, finger rail systems, etc. In some situations, cabinet components are shipped to the place of installation and assembled thereat and the on-site assembled cabinet is then mounted to the vertical wall. There are several problems with this manner of construction and installation, including for example:

(1) It is difficult for one individual to lift and hold an elevated cabinet during installation. Typically, a helper, scaffolding, or props are used to mount the cabinet onto a vertical wall.

(2) Such cabinets are usually expensive to construct and transport to the installation site.

(3) It is frequently difficult to properly square up or align the cabinet on the vertical wall.

(4) Prefabricated cabinets, or cabinets assembled on-site, sometimes do not have the correct dimensional relationships and do not fit in the space where they are to be installed, for example, the cabinet width may be greater than the width dimension of the space where it is to be installed.

Another problem in making cabinets is “racking.” A conventional cabinet has a top panel, a bottom panel, a pair of side panels having their respective top and bottom edges fastened to the top and bottom panels, and a fifth component such a back panel or diagonal back brace. The fifth component prevents racking. This problem of racking is discussed in international patent application PCT/US2005/006648, entitled “MODULAR STORAGE SYSTEM, COMPONENTS THEREFOR, STORAGE METHOD & KIT,” filed Mar. 2, 2005, which claims the benefit under 35 USC 119(e) of U.S. provisional patent application Ser. No. 60/550,252, entitled “MODULAR STORAGE SYSTEM, COMPONENTS THEREFOR, STORAGE METHOD & KIT,” filed Mar. 3, 2004.

SUMMARY

My system has one or more of the features depicted in the embodiments discussed in the section entitled “DETAILED DESCRIPTION OF SOME ILLUSTRATIVE EMBODIMENTS.” The claims that follow define my system in terms that distinguish it from the prior art and point out its non-obviousness characteristics; however, without limiting the scope of my invention as expressed by these claims, in general terms, some, but not necessarily all, of the features of my system are:

One, my system comprises a combination of a corner connector and a pair of panels. The corner connector attaches the pair of panels together substantially at a right angle to form a corner with one panel oriented substantially horizontally and the other panel oriented substantially vertically. Each panel may have substantially the same predetermined width and may be positioned to be connected so that outer longitudinal edges thereof are aligned with each other.

Two, the corner connector is at a right angle junction where the panels meet. It includes a portion that projects outwardly away from the junction including a pair of substantially planar, rigid, elongated support members, one of which terminates in a finger element, and a connector member at a point of connection between the support members. Each support member may have an inner end and an outer end, with the inner ends being connected lengthwise to form a substantially right angle junction. The finger element may be substantially planar, rigid, and elongated and may extend lengthwise along an outer end of one of the support members. This finger element may form an acute angle with respect to this one support member and may project outwardly from an outer side of the one support member that is opposite the right angle junction. The support members and the finger element each may have substantially flat opposed surfaces. The finger element has a predetermined shape adapted to fit within an elongated slot in one panel.

Three, the connector member may include a gripping structure adapted to fit within and grip an elongated slot in one of the panels. The gripping structure may include an enlarged interior portion comprising a plurality of teeth, and it may be integral with the other portions of the connector member and formed concurrently by extrusion. The support members, finger element, and the connector member are substantially equal in length and connector member is elongated, rigid, and extends lengthwise along the junction.

Four, the horizontally oriented panel may have a pair of slots therein in an underside of the horizontally oriented panel. One slot may be near one opposed end of the horizontally oriented panel and may point towards the one opposed end and the other slot may be near the other opposed end of the horizontally oriented panel and may point towards the other opposed end. Each slot may have a terminal open end at a longitudinal edge of the horizontally oriented panel. Also, each slot may be (a) substantially at a right angle with respect to a longitudinal centerline of the horizontally oriented panel, (b) extending substantially across the entire width of the horizontally oriented panel and (c) at the same acute angle with respect to the underside.

Five, the substantially vertically oriented panel may have a slot in an inner side that is substantially at a right angle with respect to a longitudinal centerline of the vertically oriented panel and may be at a predetermined angle with respect to the inner side.

These features are not listed in any rank order nor is this list intended to be exhaustive.

My system includes a modular cabinet mounted onto a wall. A wall hanger is attached to the wall in a horizontal orientation. The wall hanger has a predetermined, substantially uniform cross-sectional configuration along a predetermined length of the wall hanger. A pair of side panels are used, and each panel has a longitudinal centerline, a predetermined width, a rear edge portion having therein a cut-a-way section with a configuration substantially identical to the cross-sectional configuration of the wall hanger, an inner side, and an angular slot in the inner side of the panel that extends along at least a portion of the width of the side panel at substantially a right angle to the side panel's longitudinal centerline. The side panels are mounted to the wall hanger in a spaced apart substantially vertical orientation with the wall hanger received in the cut-a-way sections of the side panels. A horizontally oriented panel may be positioned between the side panels. The horizontally oriented panel may have opposed ends, an edge, a longitudinal centerline, a predetermined width, an underside with a pair of angular slots, each slot being near one of the ends of the horizontally oriented panel and being spaced the same predetermined distance from the ends. Each slot may be substantially a right angle to the longitudinal centerline of the third panel. The angular slots may be at an acute angle with respect to the underside and point away from each other. A pair of corner connectors as discussed above attach the panels together.

One embodiment of my method includes constructing a cabinet structure directly onto a wall. This method comprising the steps of

(a) attaching a wall hanger to the wall in a substantially horizontal orientation,

(b) mounting a pair of side panels on the wall hanger in a spaced apart substantially vertical orientation, each side panel having an inner side including a slot extending along at least a portion of the inner side,

(c) positioning adjacent the side panels a horizontally oriented panel to form corners where the side panels meet the horizontally oriented panel, said horizontally oriented panel having an underside with a pair of slots, each slot being near a corner and said slots being at an acute angle with respect to the underside, and

(d) connecting a corner connector to adjacent panels at each corner and beneath the horizontally oriented panel, each corner connector including portions that are received in the slots in the adjacent panels.

DETAILED DESCRIPTION OF SOME ILLUSTRATIVE EMBODIMENTS

As depicted in FIG. 1, one embodiment of my cabinet, identified by the numeral 10, comprises prefabricated components that are mounted directly to a vertical wall 12 at an installation site, forming the cabinet directly on the wall as the components are connected together. Because the cabinet is constructed as its components are attached to the wall 12, or to each other, or both, a single person can assemble the cabinet in place directly onto the wall without the assistance of anyone else or props. The installer may do this without the use of a tool or tools, although the installer may use a screwdriver if desired in some instances to attach some of the prefabricated components together. As discussed subsequently in greater detail, from time to time it may also be necessary to adjust the width dimension of the cabinet if the cabinet's predetermined width dimension is too wide to fit in the limited space where the cabinet is to be installed.

These modular components may be stored in a kit 14 (FIG. 1A) that is delivered to the installation site of the cabinet 10. The kit 14 may comprise a box-type package P containing four panels 16 a-16 d, four corner connectors 18, and a wall hanger 20 (FIG. 3). The panels 16 a-16 d may be rectangular and of identical or different dimensions and made from wood, plastic, particleboard, or other suitable materials. The corner connectors 18 are typically identical in cross-sectional configuration and may all be of substantially the same length, typically, substantially from 6 to 36 inches. The corner connectors 18 may all have the same length, which may be substantially equal to the width dimension w of the panels or their length may be less than this width dimension w.

A pair of panels forms each corner A through D of the cabinet 10. Upon assembling the components of the cabinet 10 directly on the substantially flat, planar exterior surface of the vertical wall 12, one panel of the pair is substantially horizontally oriented and the other panel of the pair is substantially vertically oriented. For example, as shown in FIG. 1B, upon constructing the cabinet 10 on the wall 12, the side panels 16 b and 16 d are substantially vertically oriented and the top panel 16 a and bottom panel 16 c are substantially horizontally oriented. The top panel 16 a and bottom panel 16 c each include a pair of angular slots S1 near each opposed end E4 of these panels. As best shown in FIGS. 1B and 1C, each slot S1 is spaced the same distance d₁ from these ends E4, and each slot is at a substantially right angle to a longitudinal centerline C1 of these panels. Each angular slot S1 is at an acute angle A (FIG. 2A) with respect to each panel's underside 13. The pair of slots S1 in each horizontal panel 16 a and 16 c point away from each other as best illustrated in FIG. 1B. In the embodiment depicted in FIG. 1, each slot S1 extends across the entire width w of the panels 16 a and 16 c to terminate in an opening 11 a (FIG. 1C) in an outer edge ED2 (FIG. 1B) and an opening 11 b (FIG. 1C) in an inner edge ED3.

As illustrated in FIGS. 1 and 4, each side panel 16 b and 16 d has a rear edge portion ED1 having therein a cut-a-way section 30 with a configuration substantially identical, at least in outline, to the cross-sectional configuration of the wall hanger 20. Each cut-a-way section 30 in each side panel 16 b and 16 d is of the same shape and individual cut-a-way sections 30 are in registration when these side panels are hung on the wall hanger 20 mounted on the wall 12. As illustrated in FIG. 1E, in one embodiment, a pair of angular, elongated slots S3 in an inner side S4 of the side panel 16 b, each near one opposed edge ED5, extends at a substantially right angle to this side panel's longitudinal centerline C1. When the top panel 16 a is flush with the top ends E6 of the vertical panels 16 b and 16 d, each of these slots S3 is displaced inward from its adjacent top edge at a distance d₂ that is substantially equal to the thickness of the horizontal panel 16 a that abuts its adjoining vertical panel. Each of these slots S3 in the vertically oriented panels 16 b and 16 d may extend along only a portion of the width w of this panel as depicted in FIG. 1F or across substantially the entire panel's width as depicted in FIG. 1E. As illustrated in FIGS. 1B, 1E and 1F, each of these slots S3 in the vertically oriented panels 16 b and 16 d terminates in an opening 15 in the rear edge ED3 of these panels. Using slots that do not extend across the entire width of the panels is desirable, because the strength of a panel is not unduly weakened.

As best illustrated in FIG. 2, each corner connector 18 includes a pair of substantially planar, rigid, elongated support members 22 and 24. Each support member 22 and 24 has an inner end E1 and an outer end E2. The inner ends E1 and E1 respectively of the support members 22 and 24 are integral and connected lengthwise to form a substantially right angle junction J. A substantially planar, rigid, elongated finger element 26 extends lengthwise along the outer end E2 of the support member 22. As shown in FIG. 2A, this finger element 26 forms an angle A with respect to the support member 22 and projects outwardly from an outer side S2 of this support member 22 that is opposite the right angle junction J. For example, the finger element 26 forms with respect to the support member 22 an acute angle substantially from 5 to 85 degrees. In the corner A, for example, the finger element 26 is adapted to fit snug within the elongated slot S1 in the underside 13 (FIG. 2A) of the horizontally oriented panel 16 a upon assembly of the cabinet 10 onto the wall 12.

Each corner connector 18 also includes a connector member 28, which may be elongated and rigid, and which may extend lengthwise along the junction J. The connector member 28 is at the junction J and projects outwardly away from this junction. It may be at an angle substantially from 5 to 175 degrees with respect to the other support member 24. Along the length of the connector member 28 are a series of teeth 28 a that provide a gripping structure. In corner A, for example, the series of teeth 28 a is adapted to fit snug within and bite into and grip the slot S3 in the vertical panel 16 b upon assembly on the wall 12 of the cabinet 10. As illustrated in FIGS. 1G and 1H, this configuration allows the connector member 28 to be snapped, or force fitted, into a slot S12 that does not open at an edge of a vertical panel 16 d′.

Each corner connector 18 may be an integral, unitary structure. Typically, the corner connectors 18 are formed by extruding a metal or plastic. In one embodiment an aluminum rod is extruded to form the corner connector 18. The support members 22 and 24, finger element 26, and connector member 28 may be substantially equal in length I₁, which may be substantially equal to the width w (FIG. 1) of the panels 16 a-16 d. The support members 22 and 24 and the finger element 26 each may have substantially flat opposed surfaces. The support member 24 may include an elongated groove 24 a in its exterior surface that facilitates driving a pointed tip screw through this support member to hold it firmly against an adjacent vertical panel.

As shown in FIG. 4, the wall hanger 20 is an elongated, rigid component having a hook element 20 a that extends outwardly from a back plate 20 b that is fastened to the vertical wall 12 in a substantially horizontal orientation. It may also be formed by extruding, for example, an aluminum rod. The extruded structure has cavities 20 e to reduce the amount of material used. An elongated groove 20 c extends lengthwise along the length of the wall hanger 20 to provide a thin wall section 20 d forming the bottom of the groove. Consequently, fasteners such as screws 20 f easily penetrate the thin wall section 20 d to secure the wall hanger 20 to the vertical wall 12. The wall hanger 20 may have a length I₁ substantially equal to the distance d (FIGS. 1 and 1B) between the outer sides S5 and S6 respectively of the vertically oriented panels 16 b and 16 d upon assembly of the cabinet 10, or it may be substantially longer for mounting thereon a plurality of vertically oriented panels. It may have a substantially uniform cross-sectional configuration along its entire length.

The components in the kit 14 are removed from the package P and assembled as follows, not necessarily in the order discussed unless stated expressly otherwise:

The wall hanger 20 is attached to the vertical wall 12 in a substantially horizontal orientation. Usually, the corner connectors 18 are first attached to the side panels 16 b and 16 d. The corner connectors' connector members 28 are individually inserted first into the slots S3 near the ends E4 of the side panels 16 b and 16 d. Typically, the connector member 28 is aligned and in registration with the slot S3 and pushed into this slot, forcing the teeth 28 a of the connector member 28 into this slot. The teeth 28 a resist withdrawing the connector member 28 from the slot S3. The support members 24 of the corner connectors 18 are positioned next to, and press against, an adjacent vertically oriented side panel 16 b or 16 d, as the case may be. Each support member 24 has an inner side S7 (FIG. 1B) that abuts and extends downward along the inside surface S8 (FIG. 1) of an adjacent side panel 16 b or 16 d, as the case may be.

Next, as illustrated in FIG. 1B, the pair of side panels 16 b and 16 d with the pair of corner connectors 18 respectively near the top end E6 and bottom end E7 (FIG. 1B) of these side panels is mounted to the wall hanger 20. The cut-a-way section 30 of each side panel 16 b and 16 d is aligned with a free end of the wall hanger 20. Each side panel is hung on the wall hanger 20 with the wall hanger being received in the cut-a-way sections 30 to support the side panels 16 b and 16 d so that each panel extends outward from the vertical wall 12 at a right angle and is vertically oriented. The side panels 16 b and 16 d are located along the wall hanger 20 in a spaced apart relationship at the distance d. Because the side panels 16 b and 16 d have substantially identical length and width dimensions, they are in registration.

The top panel 16 a and bottom panel 16 c are lastly positioned between the side panels 16 b and 16 d. This may be achieved prior to mounting the side panels 16 b and 16 d on the wall hanger 20, although it is a better practice to mount the side panels onto the wall hanger first as discussed above. One panel, for example, the top panel 16 a is first attached to the spaced apart side panels 16 b and 16 d. The finger elements 26 of the corner connectors 18 at the top ends E6 of the side panels 16 b and 16 d are aligned with the openings 11 b of the pair of slots S1. The top panel 16 a is pushed towards the vertical wall 12. The finger elements 26 of each corner connector 18 are inserted endwise into the openings 11 b and slide along the slots S1 as the top panel 16 a is pushed towards the vertical wall 12. In essentially the same manner the bottom panel 16 c is attached between the side panels 16 a and 16 d.

When using the side panels 16 d′, the connector member 28 is snapped into the slot S12 in this panel, and then this panel is hung on the wall hanger 20. A horizontal panel, for example, the top panel 16 a is then connected between vertical panels by aligning the openings 11 b of the pair of slots S1 with the finger elements 26 and sliding in this top panel towards the wall 12.

With the top panel 16 a and bottom panel 16 c so attached, the inner sides S9 (FIG. 1B) of the support members 22 of the connectors 18 abut and firmly bear against the underside 13 of the top and bottom panels, which have their opposed ends E4 positioned between and abutting the side panels 16 b and 16 d as illustrated in FIG. 1B. Also, the inner sides S7 of the support members 24 of the connectors 18 abut and firmly bear against the inside surface S8 (FIG. 1) of the side panels 16 b and 16 d. When the panels 16 a through 16 d all have the same width w, their edges are substantially aligned and flush with each other.

In the cabinet 10, each panel 16 a-16 b has substantially the same width w and upon assembly their opposed outer longitudinal edges ED2 and ED3 are substantially aligned with each other. As shown in (FIG. 1C), each slot S1 in the horizontally oriented panels 16 a and 16 c terminates at a longitudinal edge in an opening: the opening 11 a in the outer edge ED2 and the opening 11 b in an inner edge ED3 at a longitudinal edge of the horizontally oriented panel and being (a) substantially at a right angle with respect to a longitudinal centerline of the horizontally oriented panel, (b) extending substantially across the entire width of the horizontally oriented panel and (c) at the same acute angle with respect to the underside 13 The two slots S1 in each horizontally oriented panels 16 a and 16 d point away from each other. Each corner connector 18 is symmetrical about its latitudinal centerline C2. This structural feature enables the corner connector 18 to be inserted into either one of the two slots S1 in the horizontally oriented panels 16 a and 16 d. The corner connector 18 is simply rotated 180 degrees so its finger element 26 may be inserted into either one of the two slots S1 in the horizontally oriented panel by sliding the finger element endwise into the terminal open end of either one of the slots in a longitudinal edges ED2 or ED3, as the case may be, of the horizontally oriented panel.

If the dimensions of the horizontal panels 16 a and 16 c are longer than the dimension of the space in which the cabinet 10 is to be installed, one end E4 of each of these panels may be trimmed to reduce their lengths so the cabinet will fit into the space at the installation site. A conventional rotary table saw at the installation site may then be used to cut another slot in the underside 13 of the horizontal panels at the distance d1 from the trimmed end of the horizontal panels 16 a and 16 c. The saw blade will be set at the angle A.

Alternate Embodiments

FIG. 2B illustrates an alternate embodiment, the corner connector 18 a, having a differently sloping connector member 40, which includes teeth 40 a. The main difference between the connectors 18 and 18 a is that the connector member 40 of the corner connector 18 a is at a different angle B than connector member 28 with respect to the support member 24. This illustrates that the angle B may vary over a wide range, for example, substantially from 60 to 130 degrees. In the corner connector 18 the angle B between the connector member 28 and the support member 24 is greater than 90 degrees, for example, 115.5 degrees. In the corner connector 18 a, the angle B between the connector member 40 and the support member 24 is less than 90 degrees, for example, 72.5 degrees.

As discussed above, the horizontal panels 16 a and 16 c have their opposed ends E4 between and abutting the sides S8 of the vertical panels 16 b and 16 d. As depicted in FIGS. 2B and 2C, the horizontal panels 16 a and 16 c are overlapping and abutting the top ends E6 and bottom ends E7, as the case may be, of the vertical panels 16 b and 16 d. In the embodiment shown in FIG. 2B, a slot S10 in the vertically oriented panel 16 b points downward at an angle substantially equal to the angle B formed between the connector member 40 and the support member 24, namely, 72.5 degrees. As discussed above, upon assembly of the panels 16 a and 16 b, the connector member 40 is pushed into the slot S10. In the embodiment shown in FIG. 2C, a corner connector 18 b employs a connector member 40 a that is displaced downward along the support member 24. As discussed above, upon assembly of the panels 16 a and 16 b, the connector member 40 a is pushed into a slot S11 in the panel 16 b.

FIG. 2D illustrates an alternate embodiment, the corner connector 18 c, having a connector member 42 shaped as a “dove tail.” This shape may be used in some situations, but is not equivalent to the connector members 28, 40, or 40 a that have the teeth 28 a. For example, this “dove tail” or similar shape with an enlarged interior portion must slide into a slot having an opening at an inner edge of a vertically oriented panel and may not be used with the panel 16 d′.

FIG. 2E illustrates yet an alternate embodiment, the corner connector 18 d, having the right angle support members 22 and 24 each having ends terminating in connector members 42 a and 42 a′ shaped as “triangular cross-sectional tails.” The connector member 42 a and 42 a′ are oriented at right angles from each other and the connector member 42 a extends lengthwise along the outer end E2 of the support member 22 and the connector member 42 a′ extends lengthwise along the outer end E1 of the support member 24. This shape may be used in some situations, but is not equivalent to the connector members 28, 40, or 40 a that have the teeth 28 a. For example, the connector members 42 a and 42 a′ must slide into a slot having an opening routed out to accommodate the shape of the “triangular cross-sectional tails” of the connector members 26 a and 42 a at an inner edge of a vertically oriented panel 16 e and a horizontally oriented panel 16 f.

FIG. 2F illustrates an alternate embodiment, the corner connector 18 e, having similar to the corner connector 18 d, but “circular cross-sectional tails” at the ends the connector members 26 a and 42 a. The two “circular cross-sectional tails” 42 b and 42 b′ are oriented at right angles from each other. The connector members 42 b and 42 b′ are oriented at right angles from each other and the connector member 42 b extends lengthwise along the outer end E2 of the support member 22 and the connector member 42 a′ extends lengthwise along the outer end E1 of the support member 24. This shape may be used in some situations, but is not equivalent to the connector members 28, 40, or 40 a that have the teeth 28 a. For example, the connector members 42 b and 42 b′ must slide into a slot having an opening routed out to accommodate the shape of the “circular cross-sectional tails” of the connector members 42 b and 42 b′ at an inner edge of a vertically oriented panel 16 e and a horizontally oriented panel 16 f.

The modular cabinet may include a sheath member covering at least a portion of an exterior of the wall hanger to inhibit splitting of a side panel. The sheath member is configured so that it fits snugly about the hanger and has essentially the same profile as the cut-a-way sections in the side panel. An embodiment of such as sheath member, which may be made of a plastic, is illustrated in FIGS. 4A and 4B and designated by the numeral 100. The sheath member 100 covers the wall hanger 20 and its configured so that it fits snugly about the hanger 20 and has essentially the same profile as the cut-a-way section 30 in each side panel 16 b and 16 d. The width w1 of the sheath member 100 is essentially equal to the thickness t (FIG. 1) of, for example, the side panel 16 d. The thickness t2 of the sheath member 100 is approximately ¼ inch. The sheath member 100 inhibits splitting to the panel.

After reading the above section, one skilled in the art will understand the benefits my invention provides. These benefits include, but are not limited to, providing cabinets: (a) that are delivered to the place of installation as prefabricated components which may be assembled directly and quickly by a single installer onto a vertical wall to form the cabinet, (b) that include a corner connector that is easy to manufacture and enables a pair of panels to be quickly connected to form a corner of the cabinet, (c) that are delivered as a kit that includes all the prefabricated components needed to assemble a cabinet directly onto a vertical wall, (d) that enable an installer at the installation site, using a conventional saw, to adjust the dimensions of the prefabricated panel components so the cabinet fits into the space, at the installation site, even though it has a dimension, particularly a width dimension, less than the width dimension of the cabinet, and (e) that provide a simplified method of installing a modular cabinet using prefabricated components that may be assembled without the use of tools onto a vertical wall by a single installer without the aid of props or other types of supports.

SCOPE OF THE INVENTION

The above presents a description of the best mode contemplated of carrying out my invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains to make and use my invention.
